Patented Nov. 1929 UNITED STATES PATENT OFFICE WADE H. WINEMAN, OF MICHIGAN CITY, INDIANA, ASSIGNQR T0 SULLIVAN MA- CHINERY COMPANY, A CORPORATION OF MASSACHUSETTS SPLITTING DEVICE Application filed August 22, 1927. ,Serial No. 214,705.

My invention relates to a device for breaking or splitting bricks or other blocks.

It has for an object to provide a device for breaking blocks which shall be of an exceedingly simple and rugged character. Another object is to provide an ellicient device for cut ting oil the corners of bricks along a predetermined line particularly useful in shaping fire brick for furnaces. Other objects and advantages will however subsequently more fully appear.

In the accompanying drawing I have shown for purposes of illustration one form which my invention may assume in practice.

In these drawings,

Fig. 1 is a side elevation View of my device showing a brick in position to be cut.

Fig. 2 is a plan view of the same device, parts being broken away to facilitate illustration.

Fig. 3 is an end elevation.

Referring to the particular embodiment of my invention illustrated in the drawings, the device comprises a base portion 1 adapted to be mounted on a suitable support, said base portion having upstanding arms 2 and a cutter arm 3 is pivotally mounted on said upstanding arms. A cutting element 4: projects upwardly from the base 1 adjacent the end opposite the arms 2, and rearwardly of this cutting element is another upstanding portion 5, in which are formed a plurality of angular recesses 6 opening toward the cutting edge and adapted to receive a corner 01 the brick to be cut in a manner clearly illustrated in Fig. 2. The cutter arm has a cutting edge 7 adapted to swing to a position in the same vertical plane as the cutting edge 4 and a striking knob 8 is also formed integral with the cutter arm, preferably in vertical alinement with the cutting edge 7. Each of the arms 2 is suitably notched at 9 to provide bearings for the ends of a rod 10, which extends through and is rigidly secured to the 4.5 end of the cutter arm 3. This end of the cutter arm has a recess 11 for receiving one end of a tension spring 12 and the other end of this spring is connected to the rod 13, suitably fastened in the lower portion of the base. This spring is adapted to exert a downfull line position shown in Fig. 1 and a blow is struck on the striking knob 8, whereupon the brick parts along the plane of the cutting edges 4% and 7. The means for positioning the brick relative to the cutting edge may obviously assume various forms according to the line along which it is desired to cut the brick, the angle illustrated being designed so as to properly shape a fire brick for use in building furnaces.

Vhile I have in this application specifically described one form which my invention may assumein practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms Without departing from its spirit or the scope of the appended claims.

WVhat I claim as new and desire to secure by Letters Patent is:

1. A device for cutting bricks along a predetermined line comprising a base portion, a cutting edge projecting therefrom, means for positioning a brick in a predetermined relation to said cutting edge comprising an upstanding portion on said base rearwardly of said cutting edge and having a plurality of angular recesses therein adapted to receive a corner of the brick to be out, a pivotaL 1y mounted cutter arm having a cutting edge adapted to be positioned opposite to said first mentioned cutting edge, and a striking portion on said arm.

2. In a device for shaping bricks, a base portion, a cutting edge projecting therefrom, means having an angular recess formed therein and opening towards said cutting edge for receiving a corner of a brick to be cut, a pivotally mounted cutter arm having a cutting edge adapted to be positioned opposite to said first mentioned cutting edge, and a striking portion on said arm.

3. In a device for shaping bricks, a base portion, a cutting edge projecting upwardly therefrom, means having an angular recess formed therein and opening towards said cutting edge for receiving a corner of a brick to be cut, a plurality of upstanding arms formed integral with said base, a cutter arm having journal portions rotatably mounted in said arms, a tension spring attached to said base and said cutter arm for exerting pressure between said journal portions and said arms whereby the cutter arm is frictionally held in any adjusted position, said cutter arm having a cutting edge adapted to be positioned opposite to said first mentioned cutting edge, and a striking knob in substantially the same vertical plane as the cutting edges.

4. In a device for shaping bricks, a base portion, and means mounted on said base for supporting a brick to be cut, positioning means having an angular recess formed therein and opening toward the front end of said device for receiving a corner of the brick, a pivotallv mounted cutter arm having a cutting edge adapted to be positioned opposite said supporting means, and a striking portion on said arm.

In testimony whereof I affix mv signature.
